Test Facility

This section introduces the Test Facility. The Test Facility is built into all
AT-8800 Series software. For detailed information on operating the Test
Facility, see the Test Facility chapter of the AT-8800 Series Software Reference.
Any interfaces being tested are dedicated to the Test Facility. The Test Facility
can be thought of as a specialised interface module like PPP.
Before using the test facility, disable any configurations
(SET CONFIGURATION=NONE) and restart or reboot the switch.

Ethernet LAN Port Tests

A crossover cable is required to run an Ethernet LAN test. See "Useful Cables"
on page 18 for details of how to make a suitable cable. To start the test, loop a
four-pair crossover or straight-through cable between any two RJ-45 ports and
enter:
ENABLE TEST INT=ALL
A loopback plug, instead of a crossover cable, can be used to test SC and MT-RJ GBIC
interfaces.
All interfaces connected by crossover cables are tested. Test results are
displayed with the command:
SHOW TEST
which produces a display like that shown in Figure 9 on page 23. A more
detailed output (with frame counts) can be displayed with the command:
SHOW TEST COUNT
which is shown in Figure 10 on page 23.

Other Interface Tests

Refer to the Test Facility of the AT-8800 Series Software Reference for
information on testing other interfaces.
If a test fails, please contact your Authorised Allied Telesis distributor or
reseller.
